Some things to check:
1) Make sure driver is allowed through your PCs firewall (port 3000)
2) Phone and PC on the same LAN (can ping each other)
3) Browser to http://ipaddressofyourpcrunningdriver:3000 on the phone (the QR code tries to guess the IP but in some cases you may have more than one IP, or some esoteric networking config, in which case you should know which IP is the correct IP of the PC running the driver
